SOLUTIONS!!
Which of these problems can cause the v-belt drive to slip or squeal? - (ANSWER)insufficient tension
In what way are grid couplings different than chain couplings? - (ANSWER)Grid couplings allow for more
misalignment because they are torsionally more flexible
Which of these condition indicates that v-belt drive sheave needs to be replaced? - (ANSWER)Belt rides
more than 1/16 inch below the outer edge of the sheave groove
Before removing a machine guard to fix a machine, what step should a maintenace technician perform?

The danger of a nip point, where a part of the body or clothing can be pinched between two machine
parts, is present with all of the following power transmissions EXCEPT? - (ANSWER)Two shafts
connected with a flange coupling

machine
When should the chain on a standard roller chain drive be replaced? - (ANSWER)Elongation reaches 3%
If the power level is low to moderate, what is the most common method of verifying the correct tension
of a timing belt? - (ANSWER)Tension tester measurement of belt deflection matches specification
What factor can cause the pins on the link of a roller chain drive to rotate or to stick out? -
(ANSWER)Inadequate lubrication or excessive load
